OBJECTIVE: To compare the effectiveness of patellar denervation versus non-patellar denervation in reducing anterior knee pain on a follow-up period of at least one year after total knee arthroplasty.
METHOD: Data from 84 patients, who underwent total knee arthroplasty were analyzed. Participants were divided into 2 groups; group A: 42 patients who previously underwent total knee arthroplasty with patellar denervation; and group B: 42 patients who previously underwent total knee arthroplasty without patellar denervation. Results were evaluated using WOMAC and KSS questionnaires, and the VAS pain measurement. Knee ranges of motion were measured. Preoperative clinical conditions of both groups were similar.
RESULTS: Postoperatively, the following results were observed. (a), the WOMAC scores for group A were significant better when compared to group B (27.95 ± 5.89 vs. 33,55 ± 6.23; (b) better results were also found in KSS scores for group A vs. group B (86.19 ± 7.10 vs. 83,07 ± 4.88); (c) the range of knee flexion was smaller than in group A vs. group B (119.0 ± 10.7 vs 125.5 ± 11.0 degrees); (d) there was no significant difference between the mean of range of knee extension between the two groups groups; (e) in terms pain referred by the patient, no difference was observed according to VAS pain.
CONCLUSION: Patellar denervation does not show better effect in pain reduction compared with TKA with non-patellar denervation. However, it had a better beneficial effect on knee function score, as measured through the KSS and WOMAC questionnaires.

BACKGROUND: Street running is extremely popular worldwide. Despite its benefits, there is evidence that stressful physical activity contributes to the development of lesions on the patellofemoral joint, leading, to anterior knee pain. As an attempt to attain pain control and to improve performance, specific footwear is being developed, aiming to suit particular types of foot strike, and therefore to reduce the risk of injury.
OBJECTIVE: To evaluate the effectiveness of the use of customized shoes, based on baropodometric test, for the remission of anterior knee pain among amateur street runners.
METHODS: This is a cross-sectional study, using questionnaires based on anthropometric and anatomical data of the runner, type of training, individualized footwear based on baropodometric test and diagnosis of anterior knee pain. In total, 40 athletes were studied, which were divided into two groups: Group 1, with 19 athletes who wore specific shoes for their activity, according to the type of foot strike, and, Group 2, with 21 athletes who used neutral shoes, not prescribed by healthcare professionals. All athletes practiced at the same running field.
RESULTS: Most of the athletes were female (70%), The pain remission had no overall statistically significant difference between the two groups. However, significant differences were found between groups A and B regarding the time of occurrence and the extent of AKP.
CONCLUSION: The data analysis showed that the use of customized running shoes, based exclusively on baropodometric exams, does not reduce anterior knee pain in amateur street runners, which is consistent with current literature. The improvement of pain with customized shoes, when present, appeared to have a short duration of around three month.
